You probably won't have much to worry about until you have to decide whether screen time for your kid (at age 3-4) is a reasonable trade-off for you and your partner to have peaceful time to yourselves. Then it'll rear it's head again, after lulling you into complacency, when the kid is middle school age and all their friends have smartphones. Then you have to decide whether the convenience factor (for you) of your kid having a device is worth the trade-off of... them having a device.

Fwiw, my older two are 14 & 16 and we still use device control software on their phones and laptops. The younger of the two complains a bit periodically but the older one just accepts that it's the way it is and gets on with his life [most of the time].

I personally advise you not to let your young kid get into e-gaming. Things like Fortnite, Roblox and Minecraft are gateways to increased device usage, and the benefits are (again, imho) not remotely worth it nor irreplaceable by much healthier alternatives.

Fun tidbit: my 8yo has a Kindle Fire and we've let her have Netflix & Disney+ installed on it. She also uses the Kindle & Libby apps to read voraciously, and Khan Academy for math. When she watches streaming media, though, she frequently watches it on mute with subtitles. That shocked me to see, and I asked her about it. She's 100% cool with that and appreciate the "privacy" of being able to watch things without other people meddling in her business. Shrug.
